Letters Patent No. 92,987, lated July 27, 1869.

COFFEE-POT.

The Schedule referred to in .these Letters Patent and making part of theA same.

To all whom lt may concern:

invented and made a new and useful Improvement inv Urns for'Extracting Coffee or Tea; and we do hereby declare the following to be a full, clear, and exact (lescriptiou ofthe said invention, reference being had to the annexed drawing, making part of this specification, wherein we have represented a vertical section of the said invention.

In the coffee-pots or urns heretofore made, a diiiiculty is experienced in coating the inside of the copper vessel with sutiicient thickness of melted tin to prevent the same being rapidly worn oli in using or cleaning said vessel,'and thereby the lcopper is left exposed. y

To obviate this diiculty, we m'ake use of' a copper vessel a, with a lining made of block-tin rolled outv into sheets, and tted accurately into the inside ofthe copper vessel, as shown at b, and the two united at the joints with solder. This lining is much more perfeet and durable than any lining` heretofore employed in colee-urns.

In other characters of coiee-urus, the cover has been set inside the urn with the rim in a water-vessel. In this case, the condensation of the vapors and aroma of the coffee is lost by running int-o this water-vessel, and being thrown away with the dirty water there accumulating.

To obviate this last-named diiiculty, we place au annular water-vessel,I c, around outside the upper end of the urn, vwith a cock at (l, to allow the water to be drawn o",.for replenishing, or otherwise.

This water-ring receives the flange c of the cover f; and a second flange, g, from said coverA f, sits, within the urn a, so that all the aroma and vapors from the coee are retained, and condense on the inside of f, and ange g, and run back into the coi'ce.

A valve is applied at h to the cover j', to allow air to pass in as the coffee' is drawn.`

lc is .a cock, from which good coffee is to be drawn,

and lis a pipe and cock, coming in at the lowest part of the urn, to take away the thicker coffee or sediment. y

The bottom of the urn is made double, as at fm., to form a steam-space, into which the pipe n supplies steam, and o is the pipe for condensation. A lamp or gas might, however, take the place of the steam and false bottom.

A thermometer or heat-gauge is to beV applied to.

the urn to indicate the temperature, so thatthe attendant can regulate the same, and preventthe coffee getting toohot or to'o cold. It has been usual heretofore to place the ground coiee in abag, or stationary strainer. This is frequently left above the coffee' in the urn, and ceases to be useful. The strainer is diliicult to clean out, and the pouring of 'boiling water through the coffee in the strainer involves considerable loss of the aroma while the cover is oi. p

To remove these difficulties, we employ aperforated metallic globular coii`ee-l1older,q, formed of two half shells, hinged or clasped together, so that the coi'ee is first placed in this holder and the shells shut together, the boiling water is supplied into the urn, and then the coffee and holder are dropped into the hot Water and the cover put on. Thereby the aroma is retained, and the coffee always remains in the liquid, and its properties are fully extracted. Y What We claim, and desire to secure by Letters Patent, is-

1. The cover f, with the flange sitting down inside the cylinder of the urn, in combination with the flange -c and waterring c, as and for thepurpos'es set forth.

2. The urn for coffee or tea formed of sheet-copper,

ywith a lining of sheet-tin fitted and attached'to the inside of the copper vessel, .as and for the purpose set forth. In witness whereof, we have hereunto set our signatures, this 20th day of March, A. D. 1869.
